LOCOMOTIVE HEAD AND SIGNAL LIGHT} Patented June 12, 1906.

Application filed June 19. 1905. Serial No. 265,847.

To all whom it may concern:

-Be it known that I, DAv1D BURNFIELn,.a citizen of the United States, residing in the city and county of Denverand State of 0010- rado, have invented certain new and useful Improvements in Locomotive Head and Signal Lights; and I do declare the following to be a full, clear, and exact description of the in the art to which it appertains to make and companying drawings and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in class whereby the illuminating device which furnishes the illumination directly in front of the locomotive may also be utilized for the signal-lights necessary oncpposite sides of In my imprqved construction the ordinary reflector is provided with openings on opposite sides through which the rays of light may pass to the lenses mounted in laterally-located casings or casings located on op osite. sides of the main headlight casing; 'Iubular reflectors connected with the main reflector are preferably employed, the same increasing in size as the extend outwardly, their outer extremities eing located in front of the signal-lenses. Each auxiliary or side casing is provided with a curved slide, whereby the light may be shut ofi from the lens or the color of the light may be changed by passing a colored glass between the rays from ithe illuminating device and, the ordinary ens;

Having briefly outlined my improved construction, as well as the function itis intended to perform, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a section taken view of a headlight equippedwith my improvements. Fig. 3 is a perspective view in detail of a slide for controlling the signallights.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate theheadlightcasing, 6 the lens, 7 the illuminating device, and S'the reflector, which is funnel-shaped, being smallest at the rear and increasing in size as it extends outwardly, the diameter of its outer extremity being equal to the diameter of the lens.

To each side of the headlight-casing 5 is attached a casing 9, in which 1s set a lens 10, so located that rays of light passing at an angle of approximately forty-five degrees to thedirectlon of the trains movement will pass through the said lens. I preferably employ a tubular reflector 12 connected with the re flector 8 on opposite sides and surrounding o enings 12 formed in the main reflector. T hese reflectors 12 project outwardly toward the lenses 10, as heretofore explained.

' Slidabl mounted in each casing 9 is a curved plate 13, having a depend ng manipulating part 14 exposed exteriorly, whereby the plate 13 may be moved back and forth at will. This plate 13 contains a colored glass 15, filling an openingformed in the plate and adapted when moved to a position in front of a lens 10 to change the color of the light or the color of the rays passing there through. When it is desired to shut off the light completely from the lens 1G, the slide 13 is moved so that the opa ue partof the plate shall occupy a position rectly in front of the .lens.

Having thus described my invention, what I claim is- In a locomotive head and signal light, the combination with the main casing, its lens, the reflector and illuminating device, of auxiliary casings located on op osite sides of and projecting aterally beycn the main casing and commun cating with the'latter, the auxiliary casings being curved and having lenses located to receive rays from the illuminating device, the main reflector having openings to allow the light to pass from the illuminating device to the lenses of the auxiliary casin s, vided With colored trans arent material reflectingtubes entirely concealed by t e adapted to register with the enses of the aux- Inain and auxiliary casings, the said tubes iliary casings.

surrounding the said openings in the main In testimony whereof I affix my signature 5 {)eflector alndlibeing locateid in linedwilth and in presence of two Witnesses.
